Question

Name and draw the structural formulas for the four smallest alkanes.

(A) Methane, Ethane, Propane, Butane
(B) Methane, Ethene, Propane, Butene
(C) Ethane, Propane, Butane, Pentane
(D) Methane, Ethene, Propane, Pentane

Answer 1

The four smallest alkanes are methane, ethane, propane, and butane. Their structural formulas are CH4, CH3CH3, CH3CH2CH3, and CH3CH2CH2CH3 respectively.

Step-by-step explanation:

The four smallest alkanes are:

1. Methane: CH4
2. Ethane: C2H6
3. Propane: C3H8
4. Butane: C4H10

Here are the structural formulas for the four smallest alkanes:

1. Methane: CH4
2. Ethane: CH3CH3
3. Propane: CH3CH2CH3
4. Butane: CH3CH2CH2CH3
